After significant improvement, numbers of women entering construction have started to stagnate. What are the reasons for this and what can we do to improve? Getting more women into construction has been a long-term ambition for the construction industry. Even though there has been a lot of work done on this issue, recent data has shown that the numbers of women in the construction sector have remained pretty much the same – around 13% participation with only a negligible increase in the last 8 years. In addition, only about 9% of new apprentices are women; a figure which highlights the work still to be done when trying for more equitable gender participation in the future There are a number of factors for this disparity and a lot of ongoing work is being done to address the issues at play. This is evident even at a micro level as the industry has been incentivised to create bespoke clothing options for female workers employed onsite – there’s now a range of appropriately sized clothing for women to wear including high visibility jackets, boots and hard-wearing trousers. However, there’s a lot more work to be done to attract females into the construction industry. One of the most significant factors in female recruitment is around perception. It is clear from survey date commissioned by organisations like Keepmoat that the majority of women do not see a role for themselves in construction. Furthermore, they are also unaware of how many women are already in construction and how diverse their roles are. The Keepmoat survey showed that 56% of respondents were surprised to learn that women are represented at executive, manager and director level in construction. On hearing of these opportunities, 72% said that the industry needed to do more to highlight them. After completing the survey, 45% of young women said they were more interested in a construction career compared to only 13% before. However, the numbers remain relatively low in terms of other labour sectors. There are challenges at all levels of the industry – the representation of women in top roles in construction reveal the work still to be achieved. Only 16% of women have C-Level roles whilst only 3% of companies have a female construction manager. Additional surveys from trade bodies and contractors reveal that the gender pay gap is growing and women aren’t really aware of the different opportunities that the construction industry can offer. Here at Base Energy, we are proud of our record in recruiting the very best and most talented people regardless of their gender. We are also proud that some of our leading and most influential figures are women. We want to shout about this success and highlight to women around the country that construction needs them and that they are valued and vital members of the construction industry. Our experience also tells that women are playing an integral part in the growth of the industry. Nowhere more so that right here at Base Energy. Base Energy’s Director & Operations Manager, Shirley Hunter has been with Base Energy for the last three years and has contributed so much to our continued success. Shirley has worked with the construction industry for over 20 years and has always enjoyed the challenge: “I have always been drawn into traditional ‘male dominated’ roles such as the Japanese Shipping Industry, Logistics and the construction industry.  I tend to go for the roles that appeal to me and then let people judge me by my work ethic and commitment as well as my determination to achieve no matter what the odds.” Shirley is a fantastic example to people of how celebrating hard work and dedication can lead to career advancement and opportunity. It is these qualities which Shirley believes will have a big impact when addressing the gender imbalance within the construction: “I feel that it is up to individuals to promote the industry more and celebrate its achievements. This can be done in a number of ways; including through networking.  The construction sector is very friendly if you make the effort and push yourself outside your comfort zone. The promotion of women within the industry should happen naturally based on merit.  I went from being Commercial Manager to Director within 12 months of joining the company.” From a woman with 20 year’s experience to someone who has just entered the industry. Bethany Sutton joined Base Energy this January after enjoying a career in the beauty industry. Bethany now works for Base Energy as a Sustainability Support Manager and is thoroughly enjoying her role: “I did initially perceive the industry to be male dominated as prior to entering the industry and I was not really aware of the number of different roles that were available. I have become really invested in our work in sustainability. It has made me realise the importance and impact of construction within the current environmental climate.” “My experience at Base as a whole has been amazing. We are all treated equally, regardless of our position in the company, gender, age etc. The directors genuinely want the best for us and give us a lot of freedom in terms of what career paths we would like to progress into within construction. They support us with training courses and constant mentoring so that we can achieve as much as possible.” Another great example of available opportunities is our Sustainability Consultant, Carina Hassall who specialises in BREEAM and Flood Risk, Surface Water and SuDS. Carina has worked at Base Energy since 2013 and has extensive flood risk and sustainability experience with residential and commercial projects across the UK. Although, it’s clear more needs to be done to encourage women to take up onsite work, the career options available throughout the sector are attractive to those with a wide range of interests. Base Energy’s success is a direct result of the recruitment of people such as Carina’s who’s drive and dedication have been key to growing the business in recent years. It is well understood that such promotion has a tangible and positive impact on inspiring young women to consider future careers in the construction industry and that can only be a huge positive for the industry as it continues to face up to the challenges of the 21st century. We are proud of all our staff and want to recognise the hard work and commitment shown by our female employees. We hope that conversations continue to be had about gender equality in an effort to address the unequitable participation of females in the construction industry. We believe the strength of any organisation is dependent on those who work for it and it’s clear that opening up the industry to wider pools of talent can only make the construction industry stronger as we all move forward. For more information, please contact Base Energy Services Editor’s notes. Founded in 2008, Base Energy are a building sustainability consultancy providing expert building regulations and planning services for the built environment. We work with architects, builders, contractors, developers and surveyors to take away the complication of regulative planning restrictions and offer a guide though the whole planning process from start to finish; ensuring that projects meet full compliance.

A natural occurrence of someone walking is human induced vibrations. The effects of these vibrations aren’t life and death but can impact structures in a variety of ways, whether they’re buildings or bridges. Although not as serious as structural failure, minimising vibrations is a part of design that engineers need to largely consider in order to make people feel safe and comfortable. In this article, we’ll look at the impacts of vibrations. The Main Effects The two main effects of human induced vibrations are resonance and aeroelastic fluttering. In simpler terms, resonance happens when Object X vibrates at the same frequency as Object Y’s natural frequency. Object Y resonates with this and begins to vibrate too. Think singing to break a wine glass! Although the person singing isn’t touching the glass, the vibrations of their voice are resonating with the glass’s natural frequency, causing this vibration to get stronger and stronger and eventually, break the glass. Aeroelastic flutter happens when a force is exerted to an object which in turn makes it shake. It’s not necessarily at the same frequency as Object B’s natural vibration, but it makes Object B move all the same. When something resonates, it also flutters. But not everything that flutters is necessarily resonating. This is how confusion over disasters such as the Tacoma Bridge collapse occur — for a long time, and to this day, the event is used as a textbook example of resonance. However, it’s been argued that the bridge’s collapse wasn’t caused by resonance, but by fluttering. When human force is exerted and causes an object to vibrate, this is fluttering. Some instances would also see resonation happening too, but it wouldn’t be a certainty. Engineers must, of course, design to reduce the damage or discomfort caused by either fluttering or resonating.  Possible Effects Vibrations from human footfall, and the fluttering or resonation it can cause, can have many effects on a structure. These include: Hindering sensitive equipment. Depending on the building’s purpose, what it houses can be affected by the vibrations of people using the building. Universities, for example, may have sensitive equipment whose accuracy and performance could be damaged by vibrations. Effecting the structural integrity. The build-up of constant vibrations on a structure can, eventually, lead to structural integrity being compromised. A worse-case scenario would be the complete collapse of said structure. Effecting human health. According to research, vibrations in buildings and structures can cause depression and even motion sickness in inhabitants. Buildings naturally respond to external factors such as the wind or human footfall within. This low-frequency vibration can be felt, even subconsciously, by people. It has been argued that modern designs featuring thinner floor slabs and wider spacing in column design mean that these new builds are not as effective at dampening vibrations as older buildings are.  Wobbling bridges. One of the most famous examples of resonance, human induced vibrations, and fluttering all impacting a structure occurred with the Millennium Bridge. As people walked across the bridge, the vibrations and swaying caused oscillations in the bridge. Everyone crossing the bridge would then sway at the same time to avoid falling over, resulting in a cycle of increasing and amplifying the swaying effect. How to Prevent it Compared to old designs, contemporary structures tend to integrate thinner slabs and columns that are spaced widely, making them vulnerable to vibrations. Using structural design software at the design stage is an effective method for engineers to test footfall on a design and see the resulting vibrations. Although vibrations are something that happen naturally, engineers must consider reducing the effects of them in their designs to ensure security and comfort.

The importance of acoustic sound testing in a space should never be underestimated, especially when it comes to open-plan commercial offices writes Genghis Akay, Director at Planet Partitioning. With substandard acoustic performance one of the cardinal errors of a poorly-designed office, how important is it to test sound levels in life-like scenarios? More to the point, if an office’s acoustic performance is below par, it can have negative repercussions on employees, affecting concentration, productivity and health. Considering employees’ wellbeing is at the heart of every business, how crucial is it to test a space’s acoustic performance for the sake of its occupants? Test as true to life Whilst there are computer-simulated assessment tests available which can provide an estimate of a space’s acoustic performance, it isn’t necessarily conclusive or reliable. In most cases, these tests will not account for what happens in reality. Considering every item in a space can affect acoustic performance – from the kinds of glazing seals to the method of construction – it is crucial to test acoustics in conditions as close to its real-time use. For instance, in some testing locations, glass partition framework is buried into the ceiling and the floor. But what happens if the framework is exposed? How will this discrepancy – between testing design and real-time design – affect the space’s acoustics? Products must be tested in true-to-life scenarios to ensure there are no discrepancies between when the product is tested and when it is installed. By selecting a testing centre which analyses the real-time performance of a space, clients achieve an accurate picture and ensure noisy acoustics are kept to a minimum. As well as being more or less true to real-life use, acoustic testing must also be without influence or bias. Prior to product installation, it is essential for all acoustic testing to be executed by an independent body, in which testing locations are UKAS-accredited (United Kingdom Accreditation Service). Installation phase When it comes to product installation, flanking sound transmission is an important consideration when it comes to partitions. Flanking sound transmission is when sound passes over and is not absorbed by objects. Sound that passes around objects is more disruptive for occupants, and tends to be more present in spaces with flimsy or weaker partitions. In these kinds of spaces it is crucial to strike the right balance. If companies install a sophisticated acoustic performance glass partition between a raised access floor and a suspended ceiling, the raised access floor and ceiling must be treated properly to combat flanking sound transmission. Essentially, it is about taking a holistic snapshot of how the space will perform to ensure acoustic levels are kept to the correct minimum. Without installing the right products, the quality of the whole space will be compromised. All of the components – from the services, to the partitions, to the type of surface – have to work in harmony within the space to assure acoustic performance.

Better office design can improve people’s lives writes Genghis Akay, Sales Director at Planet Partitioning. This should be a given but it’s often surprising how many businesses don’t consider workplace design a good business investment. One thing is for sure, technology can play a huge role in the future of our office environment to meet our needs and ensure it is truly a productive space.  For designers, it’s never been more important to get the balance right to ensure technology and office design integrates seamlessly.  What tools are at the designer’s disposal to make the design and operation of offices appealing to the employee to want to come to work and interact with others? Technology continues and will continue to play a big part in the way we work. It enables us to work from almost anywhere. This flexibility may well improve the health and wellbeing of the employee but we still have a long way to go in terms of the way in which we communicate how spaces should and need to be used. It’s vitally important employees have better structured and designed rooms and be able to utilise technology to maximise productivity. Glass partitions The advent of videoconferencing has seen rapid growth, but in the modern open office environment this has a knock-on effect with acoustical challenges for the designer. Glass, drywall, wood and concrete surfaces only exacerbate the issue.  There is a need for these spaces to be soundproof so that confidential discussions can be held. Therefore, it is a case of keeping noise out, as well as in. However, there is also the need for these spaces to feel open and airy rather than claustrophobic and closed in. This is why the acoustic performance of glazed partitions is so important. Furthermore, with the invention of special LCD privacy films on glass partitions, people can see through the film both ways, resulting in total screen privacy from the outside whilst being able to see through the film on the inside. Security Security is a concern for any business, but old fashioned and inconvenient security methods are a thing of the past in the 21st century office. Remote control operated locks have had a massive uptake with co-working spaces because people don’t want to issue keys as they may be misplaced or go missing. Partition and door systems need to be designed in a way so they can incorporate new and improved smart locks that can be operated by card keys or are Wi-Fi enabled, dispensing with keys altogether. There are no additional costs for duplicate keys or the associated servicing costs for key-operated locks.  Both Planet’s IsoPro doors and EclipseTec top hung acoustic sliding glass doors have options to include innovative electronic access control devices. With the modern workplace becoming increasingly mobile, there are greater demands on designers to ensure the agile office worker has access to a wide variety of work settings along with the right tools and technology. Ultimately, a shiny new workplace may well have all the bells and whistles but it will only ever work if it accurately reflects the needs of its habitants.

The law states that on construction sites action is required to protect those at work on site and members of the public. Therefore, necessary measures must be taken to ensure the health and safety of everyone. This can include enforcing rules within the workplace for employees and making the general public aware of the dangers of entering a construction site. Only authorised personnel who meet the necessary criteria should be allowed on site at any time. Construction sites can potentially be extremely dangerous, so following these safety tips should keep you and your workforce safe while on site. Health & Safety Training It is a legal requirement that employers offer and provide training to their employees. Not doing this can lead to substantial injures or even be fatal for employees. Whilst employers can receive hefty fines for not abiding by the regulations set out to ensure employee health and safety. There are many courses available for working on construction sites, from manual handling courses to working at heights training. Ensuring all employees are trained in the required area will provide a fully qualified and highly competent workforce. One in three injures at work are caused by the manual handling of heavy objects incorrectly. Providing manual handling training will enable workers to carry heavy components in a safe manner. In 2017 falling from height was the most frequent cause of fatal accidents at work, this is surly a good enough reason to make sure any employees working at height are fully trained and qualified to do so. Not only will these injuries affect your employees, but your construction projects may suffer. If the vital work they were carrying out is halted whist they recover or a replacement cannot be found to finish the work, then the project will suffer as a consequence of this. Safety Equipment Within the construction industry there are many hazards and therefore, a vast amount of safety equipment should be used on a day to day basis to keep employees safe. This equipment includes: Fall restraints/arrest systems can be used whist working at heights to prevent injuries or even death. This will either prevent construction workers from falling in the first place or can be used to prevent fatal injuries by safely stopping a worker from falling. These systems can consist of harnesses, horizonal lifelines and vertical lifelines. Safety netting is another example of safety equipment which can be used whilst working at height. Having netting below someone working at height will allow a safe landing if they do fall. Hearing protection should be used when working with loud machinery and power tools on a construction site to protect the ears. Since prolonged periods of exposure to loud noises can cause immediate and long-lasting damage. Tool Lanyards are important types of safety equipment, as this will protect the safety of workers below. Attaching tools to a lanyard will ensure tools aren’t dropped from height onto people working, standing or walking below - which could cause considerable injuries. Protective workwear It is essential for all employees to wear the necessary protective workwear whilst on site. Some workwear is required all the time, whilst some workwear is only required in specific cases. Boots must always be worn on site for protection, since there may be potentially dangerous equipment or machinery on the ground. Also work boots will provide grip for wet and slippery surfaces, particularly in winter when it may be snowy or raining. Helmets must also be worn whenever on site to reduce the risk of head injuries, which could be caused by something being dropped or falling from above. Not only this but head injuries could also be uncured banging it on a low hanging piece of equipment such as a ladder or scaffolding. High vis should be worn to stay safe on the job. The visible clothing will not only notify other employees but also members of the public will then be aware of construction work taking place and take the necessary precautions when passing by. Sun protection is essential during the summer months, since working outside for prolonged periods can cause heat exhaustion or even heat stroke. Wearing protective clothes in the hot weather will allow breathability and protect the skin from the sun – reducing the risk of skin related diseases like melanoma. Gloves should be worn for hand protection whilst working on a construction site. Wearing gloves will protect the hands from harmful chemicals, getting cuts from sharp objects or burns. Furthermore, during the winter months gloves can keep the hands warm and supple. Face shields/masks or goggles should be used to protect the face, eyes and lungs if work being carried out emanates toxic fumes, particulate matter or hazardous chemicals. Risk Assessments Carrying out risk assessments is essential when managing health and safety in construction. A risk assessment will identify and evaluate any potential hazards or dangers on the site. In doing this the necessary control measures can be taken to ensure a safer environment. In certain construction sectors, a risk assessment is vital since employees may need to be notified about dangers which cannot be eliminated. For example, any electrical work will come with potentially severe risks which need to be recognised and employees must be advised to proceed with caution. Visible Signage Keeping employees safe is only half the battle – employers also must ensure the safety of the general public according to management regulations. Visible signage must surround the construction site giving warning to passers-by, so they are aware of the dangers of entering the premises. This could consist of signs saying, ‘Warning Construction Site’ or ‘Construction Site KEEP OUT’, they should be yellow, black or red as these are warning colours. Safety fencing should surround the site to protect more vulnerable people and children who may wander onto site unaware of the dangers. Site Organisation No matter the construction activity, the site should be organised and tidy. Slips, trips and falls account for nearly one third of injuries on construction sites, whilst 40% of fatalities are caused by slips, trips and falls. However, there is a simple solution to prevent these injuries – by organising the construction site, keeping materials and equipment out of the way and keeping the site tidy should decrease the number of accidents. Clearly in the winter when the ground is slippery, slips may be more common. Spreading grit or salt on the ground can be an easy fix to lower the chances of employees slipping.

Advancements in technology have improved most industries, including the construction and engineering sectors.  But could humans eventually find themselves redundant within these work spheres at the expense of technology?  Probably not!  After all, software is usually only as good as the human operating it… Computer-based assistance really is just that: a tool to assist. The successful link between computer programmes and engineering skill varies depending on which part of the AEC industry they are being used in. To understand how this factor can impact their relationship, we must first look at the three main stages of engineering design.  Concept design: At this stage, the majority of the design comes from the imagination of the engineer, supported by some simple sizing elements or calculations. Drafting and analysis: This stage brings the concept design into the real world more earnestly, checking that it is feasible and how it will succeed. This stage is predominantly computer-based, using, for example building design software, which strives to assist engineers work with regards to accuracy. Detailed design: This stage is when, as the name suggests, the design becomes much more detailed. At this point, the design is almost completely computer-based, with analysis happening in the background. It’s likely that such processes will always require an aspect of creativity and imagination — the ability to think outside the box and problem-solve in new ways. But it’s not just the imaginative aspect that machines cannot replicate in full: fine tuning, for example, still needs a guiding human hand in order to ensure the outputs are correct. While leaps and bounds are certainly being made in machine learning, whereby computers can now make decisions based on historical data and records, it is highly unlikely that this will develop to the point where human skill and judgement become obsolete. Naturally, human judgment is not flawless. Mistakes can be made when writing the programmes designed to support design, or further along the line when inputting data into these programmes. Either error will result in an inaccurate output. For this reason, the topic of automated checking — whereby computer programmes will check the input against previous projects and their success or failure — has been a hot point of discussion within the AEC industry lately. However, it is worth bearing in mind that the majority of engineering disasters have occurred due to something unusual; that is, something that has not happened in previous related projects. While rule-checkers help when situations where rules apply, they aren’t able to flag something that hasn’t happened in previous records, i.e. something unusual. There are many examples of such missed errors. For example, the Millennium Bridge’s well-known wobble was not picked up on at any point by the design’s code. Programmes failed to predict the wind instability of Tacoma Narrows. While engineers can make use of a value judgement, computer programmes do not. As the world changes, engineers will make a value judgement to adapt their designs accordingly. In order for both human and technological processes to be as accurate as possible, formulas need to be crafted. There are several structures and designs that have had formulas developed exclusively for them. For example, the original formula creation for shell structures had to be created by expert mathematicians to ensure success. Now, with Finite element Analysis, almost any form can be analysed — but that does not mean these forms are always sensible. There’s a certain amount of tension between architects and engineers surrounding this. Where engineers are seen as wanting functionality, architect are seen as wanting novelty first. But this disparity makes for the perfect partnership towards the best designs.        

Figures show one-in-six construction-based workers suffers from a form of mental illness. Even more alarming is the statistic that reveals suicide kills more people in the building sector than falls from height writes Steph Palmer, BriggsAmasco Training Officer. It’s also reported that two construction workers reportedly take their own life each day. Such distressing data highlights the urgent need for roofing companies and the industry as a whole to educate employees and ensure they have the best possible support in order to recognise mental stress symptoms in themselves and colleagues. In doing so, they will be taking a vital first step to making a full recovery from the debilitating effects of anxiety and depression.  Journey As a company, BriggsAmasco is facilitating an environment that encourages, where reasonably possible, improved mental health amongst employees. This journey began in 2017 when a workshop was staged as part of the company’s annual Health and Safety forum. It was held on behalf of contract-related staff and subcontractors in order to steer individuals seeking guidance towards the appropriate mental health support. Feedback from employees who attended the workshop was extremely positive. This was particularly encouraging, as BriggsAmasco aims to create an environment and culture where staff feel comfortable discussing their psychological state, whether it is good or bad.  Employers should take into account the fact that not all workers feel comfortable raising such issues with their manager, whereas others will view it as the best avenue to getting help. Listening to workers and addressing their specific needs is vital. Any staff member that is not comfortable speaking to a BriggsAmasco representative has access to the company’s Employee Assistance Programme that is 100% confidential and deals with anything from mental health issues to financial or legal problems they may be experiencing. New employees are issued with information cards, highlighting external organisations – The Lighthouse Club, Building Mental Health – which provide support to the construction community and their families. Mental health initiative BriggsAmasco hosts each new employee at its Birmingham head office for a two-day induction that includes a presentation and discussion on its mental health strategy, devised to ensure each employee has access to at least one mental health first aider on site and within its offices. Two members of BriggsAmasco staff are Mental Health First Aid (MHFA) trained and available to deliver the courses throughout the business. Since March 2019, the company has trained 35 staff as mental health first aiders; a figure that will increase in the following year. The company’s board of directors will also undergo training in mental health awareness to help continue open conversations across the company, as proof of how seriously it takes its staff’s psychological welfare.   Mental illness has long been considered something of a taboo subject within the building industry. By bringing the issue to light through its education and training initiatives, BriggsAmasco is doing all it can to safeguard its employees’ peace of mind. Visit:https://briggsamasco.co.uk/

The British Standards Institute (BSI) has published the BS 6229: 2018 - flat roofs with continuously supported flexible waterproof covering - code of practice – writes Martin Bidewell, Head of Technical and Product Management for Sika Roofing .   The latest guidelines, which were published in November, contain a number of changes in relation to general good practice guidance, updated terminology and definitions for flat roofs. These include an update of the previous definition for a “vapour control layer” to an “air and vapour control layer” (AVCL), as they perform two important functions. Changes now recommend avoiding the traditional cold roof construction, where the insulation is on the underside or cold side of the deck, due to the difficulty in forming an effective AVCL, cross ventilation and the subsequent increased risk of condensation. An additional “breather layer” is now shown over the insulation to provide an external air-leakage barrier and to help protect the insulation against any detrimental environmental factors. More specific reference on the minimum design and finished falls in formed gutters and a new definition for “zero falls” (roof slope between 0 and 1:80 with no back falls or ponding) is also now included. A small relaxation to minimum upstand heights at door thresholds to balconies and terraces only is adopted (following NHBC guidance) to allow designers to meet the Building Regulations for level access. For all other abutments, the waterproofing should still be terminated a minimum of 150mm from the finished roof level. Updated advice is available for the thermal design of inverted roofs, having now obtained improved practical experience of the actual performance of inverted roofs incorporating a water flow reducing layer (WFRL), designed to reduce the ‘cooling effect’ from rainwater. Interstitial condensation is covered in detail under its own standard, BS 5250, so has been removed from this standard. However, the updated code of practice does advise minimum thermal values for heated buildings (0.35W/m2K) are achieved at any point, to avoid surface condensation, all as per legislation guidance. Although it is anticipated many of the above mentioned amendments will take time to become established industry practice Martin Bidewell, Sika’s Head of Technical and Product Management, said those within the building sector should now be familiarising themselves with the code and following this updated guidance. He said: “Manufacturers, specifiers and the like should be obtaining copies of the standard. People need to understand what the detailed changes are and the affect it might have on our buildings. From here on in, companies should be doing their utmost to ensure all new designs incorporate the latest recommendations.” The code relating to flat roofs with continuously supported coverings was previously updated in 2003. Martin said the new guidelines provide more clarity for users. “The latest guidelines are more defined and help eliminate some of the grey areas that existed within the previous code,” he said. “The 2003 version really was an old standard, therefore the 2018 code brings it into line with the latest Building Regulations and other codes of practice. In my opinion, the latest guidelines are more streamlined and easier to understand, which can only be a good thing.” “The guidelines are vital to successful flat roofing,” Martin added. “The standard sets out the basics of how to properly design a flat roof. There will always be instances when the guidelines cannot be adhered to completely, particularly when the project involves the refurbishment of an existing roof. However, there should be no excuse to ignore the code in new-build scenarios. The BS 6229 code of practice is the go-to flat-roofing document, and along with relevant trade association guidance, should form the minimum standards the industry is looking to achieve for every roofing project.” For copies of BS 6229: 2018, visit: shop.bsigroup.com  

When it comes to construction, especially when there is a focus in commercial and industrial projects, access doors and panels are becoming an asset if not being commonly considered for projects. For many contractors, access panels are becoming a solution and option for clients looking to enhance accessibility, create versatility and functionality. Access panels may not be the first thing a client thinks of when they are seeking a wall, floor or roof solution. It is for this reason why it can be hard for contractors and builders to sell the idea of using access doors and panels; however, as will be discussed, there is so much to gain when installing an access panel and door to any project. One thing that a contractor and builder can consult with their clients to show the benefits of an access panel and door, they can demonstrate why it is they need an access panel or door. To best understand why we share the following… Purpose When it comes to access panels and doors, some clients may not realize that the panel can offer many purposes. It is for this reason that a contractor or builder will want to discuss the needs of the client with what the access panel can offer. For example, a client may think that the only way to gain or provide access to tight and not so easily accessible spaces is via a door of sorts, when in fact access panels can not only create this access point but it can also provide security. The purpose of an access panel and what the client is hoping to accomplish will allow the contractor to provide the best option and solution. When the contractor or builder can fully understand the purpose of their requirements, then they can truly define the best building solution and option. Safety and Security When it comes to commercial and industrial buildings, safety and security are two major factors for clients often wanting to invest in the best option and solution. This means that when it comes to access panels, they may not always know what an access panel has to offer. When it comes to commercial kitchens, access panels are commonly used and recommended, especially when it comes to air vents and fireproofed access panels. The installation of an access panel is a business like a restaurant, or a factory can benefit significantly from one of the many access panels available in the market. From fire to soundproof panels and air vents, access panels allow business owners to enhance the safety and security of the building. More importantly, access panels that are correctly installed and selected will adhere to building codes and requirements. Functionality Access panels can unexpectedly fulfill a gap that a client may not have realized they had. Access panels and doors provide a level of functionality that is often limited by other building solutions. A door that is meant to create access may not prevent noise transference, a hatch may not have vents to allow for smoke to escape and airtight panels may not actually prevent the seeping of outside elements. With the investment of an access panel, the functionality becomes two-fold if not more. When a client is looking to install an access panel, they can also pick an access panel that doubles as being insulated or fireproof. The functionality of a panel will massively vary based on the material that it is made from. For example, contractors would not recommend the use of plastic for any exterior installs, if anything, they would ensure that the access panel is rust proof. Budget Friendly Looking to ensure that the budget is kept can be hard. Some factors are beyond any contractor or builders’ control. From materials to labour, any time there is a change or something that was not predicted it can lead to increases in cost; however if there is one building product that a contractor can rely on to keep costs low it is the access panel. While the price will vary on the material and size, access panels can be a cost-friendly solution to any project. Depending on the size of the project and the suppliers, contractors may be able to purchase access panels at a bulk rate and discount. Builder Better and Smarter Access panels have been around for decades and centuries. Initially, they were meant just to be a wall that could be easily installed and moved; however, over time and with the progression of technology, the access panel has evolved to be so much more. When a contractor or builder can incorporate an access panel or door to their project, they are enhancing the space, but more importantly, they are building smart. Access panels offer a unique level of versatility that is unlike any building product in the market. There are very few products that a contractor or builder can use that can meet various requirements. With access panels and doors, contractors and builders can recommend them as just a door, or they can recommend a panel with added features. From insulation to security and fireproofing – the access panel enhances any space and for a fraction of a cost that some clients may think will be the best solution. Not to mention, access panels can be easily concealed to suit the surroundings – even metal access panels can be coated with a white powder that can be painted over. Going with an access panel can be both a smart investment but a problem solver as well. They are a building product that is sometimes underrated because they are not commonly used; however, thanks to contractors who are seasoned in the field and industry – they know that an access panel can do much more than just be a flat surface. To learn more about the various access panels, both clients and contractors can visit online shops such as Best Access Doors or Access Doors and Panels to see some of their top-selling panels but also speak with their knowledgeable representatives.  

The catastrophic failure of Genoa’s Morandi bridge in August in 2018 has only served to highlight how ageing bridge structures must have a maintenance regime that can ensure the safety of road users.  In the UK, rail and road bridges are subjected to many types of loadings and other influences including corrosion which has to be properly managed to maintain safety.  With nearly 100,000 road road and rail bridges across the country, what proven solutions are available to ensure this vital infrastructure is fit for the future? Three quarters of all highways bridges consist of reinforced concrete, and whilst concrete accounts for the make-up of the majority of rail bridges, these structures are also made of other materials such as cast and wrought iron. Regardless of a bridge’s properties, the long-term exposure to the elements and traffic-based wear and tear will potentially lead to a number of issues including reinforcement corrosion, excessive cracking, chloride ingress and surface erosion. The consequences of not addressing bridge repair problems will be costly and possibly even dangerous in the long-run. Therefore, evaluating the causes of the deterioration is just as important and vital to evaluating and offering the correct repair strategy. Testing is a vital part of bridge repair and protection specification. It can be carried out using various techniques including a basic visual survey, hammer testing, chloride analysis techniques, carbonation testing, concrete-to-reinforcement cover surveys and half-cell potential testing. These assessments will help play a part in Sika’s preparation of any project-specific specification offering.  Lifecycle costing and management offers bridge owners the best approach to minimising any closure times whilst increasing required periods between scheduled maintenance works. This helps incur a minimal expenditure over the structure’s full service life. Sika provides bridge owners and their maintenance managers with the right design and planning tools, followed by well-designed and proven refurbishment solutions and systems to considerably increase the time between necessary maintenance and repair cycles. As the worldwide leader in the structural-strengthening of all types of reinforced concrete structures, Sika provides a full range of fully-tested and approved strengthening systems. Rather than use steel reinforcement to strengthen columns, beams, slabs and wall, specifiers are turning to carbon fibre.Flexible and versatile with a superior strength-to-mass ratio than traditional reinforcing methods, carbon fibre allows for a significant increase in performance without adding additional significant dead load. This solution is less intrusive and quicker and easier to install compared to traditional methods. Carbon fibre strengthening comes in many different forms, plates, rods, near surface mounted plates, fabrics and shear links and are fixed using a range of high performance structural adhesives. It is increasing in popularity as a proven solution for not only reinforced concrete but also steel, cast iron, wood and masonry structures due to its strength, lightweight, easy-handling ability, durability, superb adhesion and rapid installation where downtime of a structure is in short supply. By installing Sika CarboDur® for example, it is possible to improve the load carrying capability of the bridge so it can carry additional wheel loads and be fit for modern road standards. Furthermore, ageing bridges across the UK rail industry network, many from the Victorian era, require proven solutions which minimise disruption. This widely recognised and established carbon-fibre reinforced polymer strengthening solution can be installed overnight when using the new Sika CarboHeater® to encourage earlier curing, even at lower temperatures. Fixing and futureproofing critical infrastructure such as bridges has never been more important. When it comes to the upgrade and maintenance of these vital assets, Sika has the long-term refurbishment solutions that will stand the test of time. Visit www.sika.co.uk
